Liquid Network 

What is the Liquid Network Bitcoin sidechain?

The Liquid Network is a federated Bitcoin sidechain developed by Blockstream on the Elements platform, live since 2018. Liquid Network produces deterministic blocks roughly every 1 minute and hides transaction amounts and asset types through confidential transactions. A federation of financial institutions and Bitcoin businesses secures the chain with an 11-of-15 signing threshold. The network targets exchange and broker settlement plus asset issuance — Liquid USDT, DePix, and tokenized securities are issued on it. Its native asset is L-BTC (Liquid Bitcoin).

How does L-BTC stay pegged to Bitcoin 1:1?

L-BTC is created 1:1 when Bitcoin is pegged into the Liquid Network and destroyed when Bitcoin is pegged out. Peg-ins are permissionless — any user can lock BTC and receive L-BTC. Peg-outs are permissioned: federation members must co-sign the BTC release under the 11-of-15 threshold. This asymmetric design creates a trust trade-off — holding L-BTC relies on federation key handling, unlike trustless Bitcoin layers.

Does L-BTC have its own supply or price?

L-BTC has no independent supply curve or price. Each L-BTC is minted on a peg-in and burned on a peg-out, so no maximum or total token supply is recorded — the circulating amount simply tracks how much Bitcoin is locked in the federation peg. Because every unit is redeemable 1:1 for BTC, L-BTC tracks Bitcoin's price. DropsTab classifies Liquid Network as a Bitcoin Ecosystem / Layer-2 network asset rather than a standalone token.

Is the Liquid Network secure after the September 2026 hack?

The September 2026 incident was the largest recorded breach of the federated sidechain model, so Liquid Network's security now carries a demonstrated exploit track record. A cache-verification bug in the Elements rangeproof code let an attacker mint unbacked L-BTC on September 6, 2026, draining 3,996.02 BTC from the peg reserve — the reserve fell from around 4,205 BTC to 197 BTC. The attacker returned 3,400 BTC on September 7, 2026, leaving about 602 unbacked L-BTC outstanding pending recovery.

What did the Liquid Network do to recover from the exploit?

Blockstream resumed Liquid Network block production on a corrected chain at 21:05 UTC on September 9, 2026, and released Elements v23.3.4 with the hardened fix the same day. User activity resumed on September 10, 2026. Blockstream stated that no inflation from either bug remains on the corrected chain. Per the official September 17, 2026 update, the staged recovery — replaying verified transactions, then resuming peg operations — was still under active testing.

How do I move BTC to the Liquid Network via peg-in and peg-out?

Users move BTC to the Liquid Network through a peg-in: a Bitcoin transaction to the federation-controlled address returns L-BTC 1:1, and peg-ins remained available after the September 2026 incident. The reverse peg-out requires federation signatures and was paused on September 6, 2026 pending completion of the recovery plan. With peg-outs paused and exchanges suspending L-BTC deposits and withdrawals, two-way conversion is impaired until peg operations fully resume.

Where can you buy and trade L-BTC?

L-BTC trades on a thin, venue-constrained market. Bitfinex supports BTC-to-L-BTC conversion at 1:1 with no fee; BTSE and BtcTurk are the other centralised venues, and swap services such as Boltz, SideSwap, and SideShift handle instant exchange. P2P venues include Bisq and RoboSats. No top-tier exchange order book exists beyond Bitfinex, BTSE, and BtcTurk, and venue suspensions since September 6, 2026 materially reduce exit liquidity.

How is the Liquid Network sidechain different from the Lightning Network?

The Liquid Network is a separate sidechain with its own blockchain, block production, and federation, while the Lightning Network is a system of payment channels on Bitcoin itself. Liquid Network users trust the federation's 11-of-15 signing threshold; Lightning users do not introduce a new trusted party. The two are complementary rather than competing — Liquid suits exchange settlement and asset issuance, Lightning suits small trustless payments.

Who operates the Liquid Network and did it hold a token sale?

The Liquid Federation — roughly 15 member institutions — operates the Liquid Network, with early participants including Bitfinex, OKCoin, BitMEX, and SIX Digital Exchange. Liquid Network held no token sale and raised no funding rounds for the network asset; governance rests with federation membership, not a VC cap table. Blockstream, the developing company, is venture-funded separately, and those rounds belong to Blockstream rather than to L-BTC.
